Some new musical interfaces make use of gestures to control music in a meaningful and intuitive way. A typical approach is to use the orchestra conducting paradigm, in which the computer that generates the music would be a textit{virtual orchestra} conducted by the user. However, although conductors' gestures are complex and their meaning can vary depending on the musical context, this context-dependency is still to explore. We propose a method to study context-dependency of body and facial gestures of conductors in orchestral classical music based on temporal clustering of gestures into actions, followed by an analysis of the evolution of audio features after action occurrences. For this, multi-modal data (audio, video, motion capture) will be recorded in real live concerts and rehearsals situations using unobtrusive techniques.","PeriodicalId":20448,"journal":{"name":"Proceedings of the 21st ACM international conference on Multimedia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82575848","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our method is based on random walk over bipartite graph to integrate visual information of video shots and tag information of Web videos effectively. Note that instead of treating the textual information as an additional feature for shot ranking, we explore the mutual reinforcement between shots and textual information of their corresponding videos to improve shot ranking. We apply our proposed method to the system of extracting automatically relevant video shots of specific actions from Web videos [3]. Based on our experimental results, we demonstrate that our ranking method can improve the performance of video shot retrieval.","PeriodicalId":20448,"journal":{"name":"Proceedings of the 21st ACM international conference on Multimedia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81053217","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Television is becoming smart and social; media sharing applications are transforming the way we converse and recall events and videoconferencing is a common application on our computers, phones, tablets and even televisions. The confluence of computer-mediated interaction, social networking, and multimedia content are radically reshaping social communications, bringing new challenges and opportunities. This workshop, in its second edition, provides an opportunity to explore socially-aware multimedia, in which the social dimension of mediated interactions between people are considered to be as important as the characteristics of the media content. Even though this social dimension is implicitly addressed in some current solutions, further research is needed to better understand what makes multimedia socially-aware.","PeriodicalId":20448,"journal":{"name":"Proceedings of the 21st ACM international conference on Multimedia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82991054","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we demonstrate a computational approach to automatically evaluate the aesthetics of videos, with particular emphasis on identifying beautiful scenes. Using a standard classification pipeline, we analyze the effectiveness of a comprehensive set of features, ranging from low-level visual features, mid-level semantic attributes, to style descriptors. In addition, since there is limited public training data with manual labels of video aesthetics, we explore freely available resources with a simple assumption that people tend to share more aesthetically appealing works than unappealing ones. Specifically, we use images from DPChallenge and videos from Flickr as positive training data and the Dutch documentary videos as negative data, where the latter contain mostly old materials of low visual quality. Our extensive evaluations show that combining multiple features is helpful, and very promising results can be obtained using the noisy but annotation-free training data. On the NHK Multimedia Challenge dataset, we attain a Spearman's rank correlation coefficient of 0.41.","PeriodicalId":20448,"journal":{"name":"Proceedings of the 21st ACM international conference on Multimedia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87991031","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The system includes our recently developed 3D audio technologies: 3D sound source localization (SSL) and 3D audio capture and reproduction using a low-cost and compact design microphone array. In essence, the SAMT system offers 3D audio capture capability and spatial audio perception with multiple participants at a site, which still falls short in teleconferencing solutions. In addition to being able to identify and automatically track the active speaker, the system allows more compelling visual presentation for effective communication. Requiring only a low-cost microphone array and a consumer depth camera, the proposed system runs reliably and comfortably in real time on a commodity laptop or desktop PC. With such a minimal deployment requirement, we present a variety of user experiences created by SAMT.","PeriodicalId":20448,"journal":{"name":"Proceedings of the 21st ACM international conference on Multimedia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86658717","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A robust tagging method must have the capability to meet the two challenging requirements: limited labeled training samples and noisy labeled training samples. In this paper, we investigate this challenging problem of learning with limited and noisy tagging and propose a discriminative model, called SpSVM-MC, that exploits both labeled and unlabeled data through a semi-parametric regularization and takes advantage of the multi-label constraints into the optimization. While SpSVM-MC is a general method for learning with limited and noisy tagging, in the evaluations we focus on the specific application of noisy image tagging with limited labeled training samples on a benchmark dataset. Theoretical analysis and extensive evaluations in comparison with state-of-the-art literature demonstrate that SpSVM-MC outstands with a superior performance.","PeriodicalId":20448,"journal":{"name":"Proceedings of the 21st ACM international conference on Multimedia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88561506","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Projective identity and procedural rhetoric in educational multimedia: towards the enrichment of programming self-concept and growth mindset with fantasy role-play 教育多媒体中的投射认同与程序修辞:以幻想角色扮演丰富编程自我概念与成长心态

Scott","doi":"10.1145/2502081.2502209","DOIUrl":"https://doi.org/10.1145/2502081.2502209","url":null,"abstract":"There is a growing movement in the behavioral sciences towards exploring more situated, pragmatic and ontological accounts of human learning. Positive psychology shows that a reciprocal relationship may exist between self-concept and the development of expertise, while social psychology reveals that mindsets about the nature of personal traits can have profound impacts on practice behavior. Thus, nurturing psychological constructs through the learning environment may empower students, enabling them to learn more effectively. Educational multimedia is known to support learning in a range of contexts, but its role in facilitating such self-enrichment has seldom been explored. Consequently, it is not clear which designs can aid both self enhancement and skill development. This doctoral symposium paper proposes that an interplay between projective identity and procedural rhetoric, delivered in the form of a fantasy role-playing experience, could be one such practice. Early experiments in the area of introductory programming show promise, but raise questions about external validity, educationally relevant effect sizes and how multimedia elements within the tool could be utilized more effectively to enhance these effects.","PeriodicalId":20448,"journal":{"name":"Proceedings of the 21st ACM international conference on Multimedia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76331617","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
